Have we ever discussed this overlooked exploitation film about the sleazy side of Manhattan in the swinging 60s? Sal Mineo stars as the sexually frustrated (and crypto-gay) stalker of Juliet Prowse. Elaine Stritch also appears as a lesbian.
Stylish if low-budget, and shot in vivid black & white, the whole film is available on YouTube. Link goes to a scene of Sal working out before meeting Prowse at the pool.
